OBJECTIVE:To investigate the effects of simvastatin on neurologic function and prognosis of patients with cere-bral infraction. METHODS:A total of 82 patients with cerebral infarction selected from our hospital during Jan. 2015 to Jul. 2016 were divided into observation group and control group according to random number table,with 41 cases in each group. Control group received routine thrombolytic therapy and Aspirin enteric-coated tablets 100 mg orally,qd. Observation group was additional-ly given Simvastatin tablets 10 mg,qd,on the basis of control group. After 1 month of treatment,prognosis,ADE as well as NI-HSS scores before and after treatment were compared between 2 groups. Multiple factor Logistic regression analysis was conducted for clinical information of patients. RESULTS:The excellent rate of prognosis in observation group was 80.49％,which was signifi-cantly higher than 68.29％,with statistical significance(P<0.05). The incidence of intracranial and extracranial vascular stenosis, brain-heart syndrome and death in observation group were 36.59％,19.51％,0,which were significantly lower than 46.34％, 36.59％,7.32％ of control group,with statistical significance(P<0.05). At admission,there was no statistical significance in NI-HSS scores between 2 groups(P>0.05). After 1 month of treatment,NIHSS scores of 2 groups were decreased significantly,and the observation group was significantly lower than the control group,with statistical significance(P<0.05). Age >65 years,NI-HSS score <4 points at admission,combined diabetes,non-use of statins were independent risk factors which affected the survival of patients with cerebral infarction(P<0.05). CONCLUSIONS:Simvastatin can significantly improve the neurologic function and prognosis of patients with cerebral infarction,and reduce the incidence of ADE. Non-use of statins is an independent risk factor which affects the survival of patients.

Objective To investigate radiological diagnosis of ossifying fibroma of long bone.Methods The imaging features in 16 patients with ossifying fibroma of long bone confirmed by pathology and surgery were analysed.All 16 patients underwent radiographic examinations,of them,CT was performed in 8 patients,MR was performed in 3 patients.Results In 16 cases,ossifying fibroma was accurately diagnosed by X-ray in 11/16 cases,by CT in 7/8 cases.MR imaging was commonly superior to CT in showing the relationship between the lesions and isthmus.Conclusion CT scan can improve the diagnosis of ossifying fibroma of long bone,and is better in demonstrating the extension of fesions than X-ray plain film,which is important for guiding clinical treatment,and MRI can be used as an important supplemental method.

Objective To evaluate the efficacy and safety of endoscopic mucosal resection (EMR) for rectal carcinoid tumors. Methods From January 2006 to January 2009, EMR was performed in 28 patients with rectal carcinoids, who were followed up to evaluate the therapeutic effect and safety. Results Tumor diameters varied from 0.4 cm to 1. 2 cm (mean 0.7± 0. 2 cm). Negative resection margin was a-chieved in 26 cases (92. 9% ), tumor margin within 0. 1 cm of resection margin in 1 (7. 1% ) , and two margins coincided in 1 patient (7. 1% ). Hemostasis was performed with metal clips in 14 patients (50% ) and argon plasma coagulation (APC) in 9 (32. 1% ). Except for rectal bleeding in 1 patient (3. 6% ) , no other complications were observed. There was no recurrence in any patients during a follow-up of 6-36 months. Conclusion EMR is a useful and safe method for treatment of small rectal carcinoid tumor which does not cross submucosal layer.

The peroxisome prolifrator-activated receptors(PPARs)? and ? constitute a subfamily of nuclear receptors. PPAR? has been shown to be activat ed by the hypolipidemic drugs of the fibrate class; While the antidiabetic TZD a re synthetic ligands for PPAR?. Upon binding and activation by their ligands, t hey regulate the transcription of numerous genes involving lipid metabolism and insulin resistance. The research indicated that PPAR? also plays a key role in lipid metabolism. PPARs therefore constitute interesting targets for the develop ment of single and dual agonists useful in the treatment of obesity and type 2 d iabetes.

Objective: To investigate the effects of calcitonin on human breast cancer cell line T47D. Methods: The inhibition rates of salmon calcitonin (sCT) on T47D cells were measured by MTT methods. Then telomerase activity of T47D cells was detected using PCR ELISA methods. Cell apoptosis was observed by transmission electron microscope (TEM). Animal models in vivo were constructed by implanting T47D cells subcutaneously into nude mice. After injection of sCT for 30 days, tumor diameters were measured. The structure of lumbar 3 were separated and compared by a scanning electron microscope (SEM). Results: The inhibitory effects of sCT on T47D cells was observed by MTT method. The PCR ELISA method discovered that sCT could decrease the telomerase activity of T47D cells. TEM found cell apoptosis induced by sCT. Tumor diameters in sCT treatment group showed no statistical difference compared with the control group. SEM of lumbar 3 discovered that sCT could strengthen the bone structure of nude mice. Conclusions: The decrease of telomerase activity and induction of apoptosis are new mechanisms of sCT inhibition on T47D cells. The tumor inhibition in vivo was not observed. This may be attributed to the complicated endocrine response in vivo . sCT is still effective in strengthening the bone structure of those nude mice without osteoporosis.

Objective To evaluate the efficacy and safety of fluoroscopy guided frequency-doubled double-pulsed laser lithotripsy for removing difficult bile duct stones. Methods From March 2008 to December 2009, patients with difficult bile duct stones were divided into cholangioscopy guided group ( n = 21 )and fluoroscopy guided group ( n = 19) to receive corresponding treatments. The success rate of complete stone removal and the complication rate related to the procedure were compared between the two groups.Results There are no significant differences between 2 groups in regarding of either success rate of complete stone removal ( 19/21, 90. 5% in cholangioscopy guided group vs. 17/19, 89. 5% in fluoroscopy guided group, P ＞0. 05 ) or rate of procedure related complication (4/21, 19. 0% in cholangioscopy guided group vs. 3/19, 15. 8% in fluoroscopic guided group, P = 0. 559 ). Conclusion Frequency-doubled doublepulsed laser lithotripsy guided by cholangioscopy or fluoroscopy are both safe and effective.

Objectiye To evaluate the therapeutic efficacy and safety of (endoscopic sphincterotomy, EST) plus balloon dilation for difficult bile duct stones. Methods Patients with difficult common bile duct stones on endoscopic retrograde cholangiopancreatography (ERCP) from March 2008 to December 2009 were randomly divided into 2 groups to receive EST or EST plus balloon dilation ( EST + EPBD), respectively. The success rate of complete stone removal, number of endoscopic sessions, the rate of using mechanical lithotripsy and the complication rate related to the procedure were compared between the 2 groups. Results Compared with EST alone, EST plus balloon dilation resulted in similar outcomes in terms of overall successful stone removal rate (2/62 vs. 2/61 ) and early complication rate (4/62 vs. 6/61, P ＞0. 05). However,EST group needed more sessions ( EST 15/46 vs. EST + EPBD 5/57, P ＜0. 05) and use of mechanical lithotripsy to achieve complete removal of stones ( EST 12/61 vs. EST + EPBD 4/61, P ＜0. 05 ). Conclusion EST plus balloon dilation is as safe and effective as, but more convenient than EST, for endoscopic removal of common bile duct stones.

Objective To study the application of pulmonary angiography and reconstruction techniques with 16-detector row spiral CT in the diagnosis of pulmonary embolism (PE) in the elderly.Methods Twenty-four elderly patients with suspected pulmonary thromboembolism received detection of CT and pulmonary artery angiography ( CTPA ) on 16-detector MSCT.Post-reconstruction techniques included maximum intensity projection (MIP), volume rendering (VR)and multiple planar reformation (MPR). Results A total of 161 pulmonary artery thrombi were detected in 24 elderly patients. The direct signs of pulmonary embolism included total occlusion (16.8%, 27/161), partial filling defect (67.7%, 109/161) and central filling defect or track sign (15.5%, 25/161). A total of 161 pieces of pulmonary thrombi were detected in transect image, 153 (95.0%) in MPR, 113 (70.2%) in MIP and 69 (42.9%) in VR. The transect image excelled evidently MIP and VR image in displaying pulmonary thrombi, especially the thrombi in pulmonary lobe and pulmonary artery branch (χ2 =235.36 and 243.41, P＜0.05). Conclusions The 16-detector row spiral CT pulmonary angiography is non-invasive, fast and high sensitive, it should be the first choice for the diagnosis of PE in the elderly.

Objective To investigate the variation of brain inhibitory function of depressed patients during the processes of the Stroop color-word interference task with the Magnetic source imaging ( MSI) technology. Methods Twenty-three depressed patients and twenty age-,gender- and education- matched healthy controls were involved in the Stroop word-color interference test to detect the variation of brain inhibitory function by magnetoen-cephaloraphy scanning. Results Compared with the healthy controls,the abnormal activities in depressed patients during different time periods were separately as follows: increased activation in the bilateral thalamus( t = 2.46, t = 2.92 ) ,the right temple fusiform gyrus ( t = 1. 81) , the right middle temporal gyrus ( t = 1. 76) , the right inferior frontal gyrus( t = 2.28) , the left anterior cingulate( t = 2.00) , the left caudate head( t=1.81) ,the precentral gy-rus( t = 2.17) ,the right parahippocampal gyrus( t = 2.04) ,the left superior temporal gyrus(t = 2.47) ; decreased activation in the right superior temporal gyrus( t=1.76) ,the bilateral middle frontal gyrus(t=1.95, t = 2.09), the right cuneus( t=1.97) ,the cingulate gyrus( t=1.70, t = 2.08) ,the postcentral gyrus( t = 2.57, t = 2.65) , the left supramarginal gyrus( t = 2. 16) ,the left lentiform nucleus putamen( t = 2.39) ,the bilateral middle temporal gyrus (t = 2.22, t= 1.90) ,the left insula( t= 1. 81) ,the left superior temporal gyrus( t= 1.90) ,the right parietal lobe( t= 3.26). Conclusion The abnormal activation inefficiency in the brain regions related with inhibition function is reflected in depressed patients,and the ability against interference information declines.
